SULKY-SPRING.

SPECIFICATION formingpart of Letters Patent No. 275,445, dated April 10,1883.

Application filed August 19, 1882.

To all whom it may concern:

Be it known that I, ISAAC A. WESSON, of Wingo, in the county of Gravesand State of Kentucky, have invented certain new and useful Improvementsin Sulky-Springs; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which 7 it pertains to make and use thesame.

My invention relates to improvements in sulky-springs, the object of thesame being to combine the seat and springs with the shafts in suchamauner that the driver will not be subjected to the sudden jars usuallyexperienced'while riding in sulkies of ordinary construction; and withthese ends in view my invention consists in the parts and combinationsof parts, as will be more fully described, and pointed out in theclaims.

The accompanying drawing represents my invention in side elevation withone wheel removed.

A represents the ordinary shafts of the sulky; B, the sulky-body, and 0two longitudinal cleats secured to the said body on opposite sidesthereof.

D are four curved springs, arranged in pairs on opposite sides of thebody, and rigidly secured at their lower ends to the cleats 0. Thesesprings can be any convenient height, and each is provided at its upperends with a loose ring, E, through which the seat-supporting straps Fpass.

G is the drivers seat, provided on its under surface, near its oppositesides, with the semi-elliptic springs G. These springs are centrallysecured to the bottom of the seat, with their concavity downward, andeach one is also provided on opposite ends with the rings E, throughwhich the Seat-supporting straps F also pass. The springs D, on the sameside of the sulky, are separated for a distance nearly equalto thelength of the semi-elliptic spring G, on the same side thereof, so thatthe supporting-straps F will hang in nearly a vertical position. Thesesupporting-straps (four in number) are made of leather or other suitableflexible material, and are provided at suitable intervals apart withperforations, through which are inserted keys afor the purpose ofholding the parts together. The straps are first passed throughtheir re-(No model.)

spective rings, as shown, and then both ends of each strap are passedthrough the ring E. The seat is then vertically adjusted to suit thedriver, and the keys at then passed through the perforations in thestraps below the rings E, and form stops, on which the seat rests. Thefree ends of the four straps are then secured to the cleats (J by thesame bolts which secure the springs D to the said cleats, or in anyother suitable manner, the straps F being sufficiently slack, however,to enable the seat to move laterally and longitudinally when the wheelor wheels come in contact with obstructions or when riding over unevenground. By securing the lower ends of the straps to the sulky-body theswinging or vibratory motion of the seat is limited. The straps F,besides performing the function of limiting the movement of the seat,also form a flexible connec tion betweenthe verticaland horizontalsprings, and admirably adapt the improvement for use on rough roads.

It is evident that slight changes in the construction and relativearrangement of the dil ferent parts might be resorted to withoutdeparting from the spirit of my invention, and hence I would have itunderstood that I do notlimitmys'elfto the exact construction shown anddescribed, but consider myself at liberty to make such changes andalterations as come within the spirit and scope of my invention.

Having fully described my invention, what I claini as new, and desire tosecure by Letters Patent, is-- 1. In' a vehicle, the combination, withthe body, seat, and springs D and G, of the rings E and E, flexiblestraps l and means for adjusting the straps to raise or lower the seat,substantially as set forth.

2. The combination, with the body, seat, and springsD G, of the rings EE and flexible straps F,secured" to said rings, and at their lower endssecured to the body, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

ISAAC A. WESSON.
